    Preventing Distributed Denial-of-Service Attacks on the IMS Emergency Services Support through Adaptive Firewall Pinholing

    Full text link
    Emergency services are vital services that Next Generation Networks (NGNs) have to provide. As the IP Multimedia Subsystem (IMS) is in the heart of NGNs, 3GPP has carried the burden of specifying a standardized IMS-based emergency services framework. Unfortunately, like any other IP-based standards, the IMS-based emergency service framework is prone to Distributed Denial of Service (DDoS) attacks. We propose in this work, a simple but efficient solution that can prevent certain types of such attacks by creating firewall pinholes that regular clients will surely be able to pass in contrast to the attackers clients. Our solution was implemented, tested in an appropriate testbed, and its efficiency was proven.Comment: 17 Pages, IJNGN Journa

    Get PDF
    The California State University is a consortium representing 23 campuses that went live on Alma in June 2017. This presentation shares the steps we took for a successful migration of our electronic resources. While the focus is on a consortium that used several different electronic resources management systems, many of the topics covered are also relevant for standalone libraries. We\u27ll provide you with pre- and post-ERM checklists to help navigate the transition from your ILS to Alma. We\u27ll discuss the advantages of having a task force and policies to provide oversight and guidance in decision making. We’ll help you prepare for the P2E List, develop search queries specific to ERM, and we’ll talk about link resolver migration issues, whether SFX, Serials Solutions or others. We’ll touch on what\u27s involved with setting up Google Scholar, Integration Profiles, and General Electronic Services. We\u27ll leave you with lessons learned, practical ideas and action items for your migration

Apart from providing infrastructures, platforms and software as a service, mechanism for dynamic allocation of compute and storage resources on-demand, commonly termed as “elastic cloud computing” account for the most important cloud computing functionalities. Resource elasticity allows not only for efficient internal compute and storage resource consumption, but also, through so called hybrid cloud computing mechanisms, for dynamic utilization of external resources on-demand. This capability is especially useful in order to cost-efficiently cope with peakworkloads, allowing service providers to significantly reduce usually required over-provisioned service infrastructures, allowing for “pay-per-use” cost models. With a steadily growing number of cloud providers and with the proliferation of unified cloud computing interfaces, service providers are given free choice of flexibly selecting and utilizing cloud resources from different cloud providers. Cloud brokering systems allow for dynamic selection and utilization of cloud computing resources based on functional (e.g. QoS, SLA, energy consumption) as well as nonfunctional criteria (e.g. costs). The presented work focuses on enhanced cloud brokering mechanisms for telecommunication service platforms, enabling quality telecommunication service assurance, still optimizing cloud resources consumption, i.e. saving costs and energy. Furthermore this work shows that by combining cloud brokering mechanisms with standardized telecommunication service brokering mechanisms an even greater benefit for telecommunication service providers can be achieved as this enables an even better cost-efficiency since different user segments can seamlessly be served by allocating different cloud resources to them in a policy-driven manner

    Dissertação (mestrado)—Universidade de Brasília, Faculdade de Ceilândia, Programa de Pós-Graduação em Ciências e Tecnologias em Saúde, 2020.Introdução: o paciente hospitalizado possui alto risco de sofrer eventos adversos relacionados à farmacoterapia. Para lidar com este cenário sugere-se a implantação de Serviços de Farmácia Clínica (SFCs), nos quais os farmacêuticos prestam cuidado ao paciente de forma a otimizar a farmacoterapia, promover saúde e bem-estar, e prevenir doenças . Objetivo: avaliar a implantação do SFC nos hospitais públicos da Secretaria de Estado de Saúde do Distrito Federal (SES/DF). Método: estudo observacional de Triangulação Metodológica, baseado em cinco etapas: (i) relato do processo de implantação do SFC; (ii) apresentação da sua estrutura e atividades; (iii) análise de um banco de dados com indicadores de intervenções farmacêuticas (IFs); (iv) percepção do serviço sob a ótica dos profissionais da equipe de saúde; e (v) identificação dos desafios e facilidades para seu desenvolvimento. Resultados: o SFC foi implantado nos 15 hospitais da SES/DF, em um processo coordenado pela Diretoria de Assistência Farmacêutica (DIASF). Nos três primeiros anos, considerando uma amostra de 12 hospitais, 36 farmacêuticos clínicos acompanharam 73.557 pacientes-dia e registraram 22.416 IFs, com uma taxa de aceitação de 82,4% na classe médica, e de 97,8% com outros profissionais de saúde. A maior parte das IFs (66,9%) ocorreu na etapa de prescrição, e a sinalização informativa foi a principal estratégia de intervenção (43,9%). A taxa de cobertura esteve fortemente associada à densidade de farmacêuticos clínicos por leito (rs=0,788; p=0,002). O SFC foi positivamente avaliado pelos profissionais da equipe de saúde, e se verificou melhora significativa da postura profissional do farmacêutico ao longo do tempo. A boa relação/apoio da equipe médica foi apontada como a principal facilidade para o desenvolvimento da atividade, e a escassez de recursos humanos, o principal desafio. Entre as limitações citam-se a falta de mensuração dos custos de implantação e manutenção do serviço, bem como a carência de indicadores que considerem resultados clínicos e econômicos. Conclusões: o estudo apresentou um processo de implantação do SFC bem sucedido. O serviço se mostrou relevante para a otimização da farmacoterapia, e foi favoravelmente avaliado pela equipe de saúde. Os achados reforçam a importância da participação do farmacêutico clínico na equipe de saúde, tanto para promover da racionalidade e segurança da farmacoterapia, assim como para contribuir com um processo de cuidado com melhores resultados clínicos, humanísticos e econômicos.Introduction: the hospitalized patient has a high risk of suffering adverse events related to pharmacotherapy. To deal with this scenario, it is suggested the implementation of Clinical Pharmacy Services (CPSs), in which pharmacists provide patient care in order to optimize pharmacotherapy, promote health and well-being, and prevent diseases. Objective: to evaluate the implementation of the SFC in public hospitals of the Department of Health of the Federal District (DH/FD). Method: observational study of Methodological Triangulation, based on five steps: (i) report of the CPS implementation process; (ii) presentation of its structure and activities; (iii) analysis of a database with pharmaceutical interventions (PIs) indicators; (iv) perception of the service from the perspective of health team professionals; and (v) identification of challenges and facilities for its development. Results: the CPS was implemented in the 15 hospitals of DH/FD, in a process coordinated by the Pharmaceutical Management Directory (PMD). In the first three years, considering a sample of 12 hospitals, 36 clinical pharmacists followed 73,557 patient-days and registered 22,416 PIs, with an acceptance rate of 82.4% in the medical class, and 97, 8% with other healthcare professionals. Most of the PIs (66.9%) ocurred at the prescription stage, and informational advice being the main intervention strategy (43.9%). The coverage rate was strongly associated with the ratio of clinical pharmacists per bed (rs = 0.788; p = 0.002). CPS was positively evaluated by health team professionals, and there was significant improvement in professional posture of the pharmacist over time. The good relationship/support of the medical team was identified as the main facility for the development of the activity, and the scarcity of human resources, the main challenge. Among the limitations are the lack of measurement of the costs of implementing and maintaining the service, as well as the lack of indicators that consider clinical and economic results. Conclusions: the study showed a successful CPS implantation process. The service proved to be relevant for the optimization of pharmacotherapy, and was favorably evaluated by the health team professionals. The findings reinforce the importance of the participation of the clinical pharmacist in the health team, both to promote the rationality and safety of pharmacotherapy, as well as to contribute to a care process with better clinical, humanistic and economic results

    Sensors, actuators and devices that compose the Internet of Things (IoT) world are becoming more diverse every day in terms of capabilities and amount of generated traffic. Current Machine-to-Machine (M2 M) communication standardization efforts try to formalize the interfaces between M2 M nodes based on the perspective of exchanging uniform small data size with low sampling rate only. However, many devices will require support for more heterogeneous traffic patterns, with different network capacity. This paper introduces a communication concept for supporting gracefully a heterogeneous set of devices. This paper analyses the effect of traffic size in M2 M transactions and propose a concept to adapt gracefully to support heterogeneous traffic patterns in M2 M systems. To prove its feasibility, the concept is exemplified on top of oneM2 M architecture and implemented as part of the Fraunhofer FOKUS OpenMTC toolkit. Additionally, the concept was applied to a deployment in an E-Health pilot and practical measurements during functional evaluation are reported
